ATF16V8CZ
Rev. 0453C/V16FZ-C–04/98
Description (Continued)
The ATF16V8CZ is a high performance EECMOS Programmable Logic Device which utilizes Atmel’s proven electrically erasable Flash memory technology. Speeds down to 12 ns and a 25 μA edge-sensing power down mode are offered. All speed ranges are specified over the full 5V ± 10% range for industrial temperature ranges; 5V
± 5% for commercial range 5-volt devices.
The ATF16V8CZ incorporates a superset of the generic architectures, which allows direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. Eight outputs are each allocated eight product terms. Three different

modes of operation, configured automatically with software, allow highly complex logic functions to be realized.
The ATF16V8CZ can significantly reduce total system power, thereby enhancing system reliability and reducing power supply costs. When all the inputs and internal nodes are not switching, supply current drops to less than 2 5 μA. This automatic power down feature allows for power savings in slow clock systems and asynchronous applications. Also, the pin keeper circuits eliminate the need for internal pull-up resistors along with their attendant power consumption.
*NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Note:
1.Minimum voltage is -0.6V dc, which may undershoot to - 2.0V for pulses of less than 20 ns. Maximum output pin voltage is Vcc + 0.75V dc, which may overshoot to 7.0V for pulses of less than 20 ns.
